Talking about messy science--does anyone know whether there is a biography,
or even intellectual history of Hugh Everett and his relative wave theory of
QM, now known as the multiverse theory?

I am doing research on how that theory and the various debates about and
within QM concerning the collapse of the wave function which actually is an
anomoly to Kuhn's theory of scientific revolution. However, what I would
like to know is--why did Everett leave physics given that he developed one
of the most revolutionary and original theories in the history of QM?
